Mechanism of Wendan decoction in preventing obesity by regulating multiple signal pathway networks based on gene promoter methylation

Objective:To investigate the potential mechanism of Wendan decoction in obesity by screening target genes with promoter region methylation changes and constructing a multiple signaling pathways network based on promoter methylation.Methods:The methylation degree of Itgad,Col8a1,Adra2b,Jund,Rab2a,Wnt8b,Fzd9,B4galt7,Pik3cd,Creb1,Stard8,and Mmp1 in the abdominal adipose tissue of obese rats was determined using the Agena MassARRAY system.Western blot was performed to assess protein expression levels.Target genes were identified based on the methylation degree in the promoter region and protein expression.Enrichment analysis of signaling pathways was conducted to identify relevant target genes and obtain a multiple signaling pathway network associated with obesity.Core and terminal effector molecules in the pathway networks were selected as research targets for reverse transcription-polymerase chain reaction(RT-PCR)analysis.Results:Four genes(Adra2b,Creb1,Itgad,and Pik3cd)showed a degree of promoter methylation consistent with their respective protein expression levels.Among them,Adra2b,Creb1,and Pik3cd expression increased,while that of Itgad decreased.Enrichment analysis revealed that Creb1 and Pik3cd were involved in 6 signaling pathways related to obesity:tumor necrosis factor(TNF)signaling pathway,growth hormone synthesis/secretion and action,adenosine 5'-monophosphate-activated protein kinase(AMPK)signaling pathway,relaxin signaling pathway,cyclic nucleotide(cAMP)signaling pathway,and phosphatidylinositol 3-kinase/protein kinase B(PI3K/Akt)signaling pathway.Subsequently,a multiple signaling pathways network was constructed based on promoter methylation.Key molecules including protein kinase B(AKT),mechanistic target of rapamycin complex 1(mTORC1),and unc-51 like autophagy activating kinase 1(ULK1),as well as terminal effector molecules interleukin-1β(IL-1β),interleukin-6(IL-6),and chemokine(C-X-C motif)ligand 2(CXCL2)were selected as research targets.Wendan decoction decreased the expressions of AKT,mTORC1,IL-1β,IL-6,and CXCL2 while up-regulating ULK1 expression.Conclusion:The mechanism of Wendan decoction in preventing obesity involves the regulation of multiple signaling pathways through the control of Creb1 and Pik3cd gene promoter methylation.However,the associated multi-path gene regulation mechanism in preventing obesity is complex.Thus,further exploration is needed to elucidate the role of methylation changes in this mechanism.

Therapeutic effect of Wendan Decoction combined with mosapride on gastroesophageal reflux disease after esophageal cancer surgery

BACKGROUND Gastroesophageal reflux disease(GERD)is a common complication of esophageal cancer surgery that can affect quality of life and increase the risk of esophageal stricture and anastomotic leakage.Wendan Decoction(WDD)is a traditional Chinese herbal formula used to treat various gastrointestinal disorders,such as gastritis,functional dyspepsia,and irritable bowel syndrome.Mosapride,a prokinetic agent,functions as a selective 5-hydroxytryptamine 4 agonist,enhancing gastrointestinal motility.AIM To evaluate the therapeutic effects of WDD combined with mosapride on GERD after esophageal cancer surgery.METHODS Eighty patients with GERD were randomly divided into treatment(receiving WDD combined with mosapride)and control(receiving mosapride alone)groups.The treatment was conducted from January 2021 to January 2023.The primary outcome was improved GERD symptoms as measured using the reflux disease questionnaire(RDQ).The secondary outcomes were improved esophageal motility(measured using esophageal manometry),gastric emptying(measured using gastric scintigraphy),and quality of life[measured via the Short Form-36(SF-36)Health Survey].RESULTS The treatment group showed a notably reduced RDQ score and improved esophageal motility parameters,such as lower esophageal sphincter pressure,peristaltic amplitude,and peristaltic velocity compared to the control group.The treatment group showed significantly higher gastric emptying rates and SF-36 scores(in both physical and mental domains)compared to the control group.No serious adverse effects were observed in either group.CONCLUSION WDD combined with mosapride is an effective and safe therapy for GERD after esophageal cancer surgery.It can improve GERD symptoms,esophageal motility,gastric emptying,and the quality of life of patients.Further studies with larger sample sizes and longer follow-up periods are required to confirm these findings.

Effects of Jiawei Wendan decoction on hippocampal p-CREB protein expression in a rat model of depression

BACKGROUND： Jiawei W＇endan decoction can elevate hippocampal brain-derived neurotrophic factor （BDNF） protein expression in rats with depression. It has been hypothesized that Jiawei Wendan decoction can exhibit antidepressant effects through the hippocampal signal transduction pathway of cyclic adenosine monophosphate response element binding protein （CREB）-BDNF. OBJECTIVE： Using phosphorylated-CREB （p-CREB） as an entry point, the present study was designed to observe intervention effects ofJiawei Wendan decoction compared with fluoxetine. DESIGN, TIME AND SETTING： A randomized, controlled, cellular biology experiment was performed at the Central Laboratory of Guangxi University of Traditional Chinese Medicine, MATERIALS： A total of 40 healthy, male, Sprague-Dawley rats were included in the present study. Rhizoma Acori Talarinowii （Shichangpu）, Flos Albiziae （Hehuanhua）, Rhizoma Pinelliae （Banxia）, Caulis Bambusae in Taeniam （Zhuru）, Fructus Aurantii Immaturus （Zhishi）, Poria （Fuling）, and Radix Bupleuri （Chaihu）, the primary ingredients ofJiawei Wendan decoction, were purchased from First Affiliated Hospital of Guangxi University of Traditional Chinese Medicine. The raw drug was decocted at a concentration of 1.5 g/mL. Fluoxetine capsules were purchased from Shanghai Zhongxi Pharmaceutical Co., Ltd., China. METHODS： Following behavioral testing, 36 rats were selected from the initial 40 rats according to similar behavioral scores, and were randomly divided into 4 groups： model （n = 8）, Jiawei Wendan decoction-treated （n = I 0）, fluoxetine-treated （~ = 10）, and normal control （n = 8）. All rats, except for those in the normal control group, were separately raised in a chronic and unpredictable, mild-stimulation environment for 2 l days to establish a depression model. The Jiawei Wendan decoction-treated and fluoxetine-treated groups were intragastrically administered Jiawei Wendan decoction （12 g/kg/d） and fluoxetine （1.8 mg/kg/d）, respectively. The model and normal control groups received double-distilled water （2 mL/kg/d） once a day for a total of 21 days. MAIN OUTCOME MEASURES： Prior to depression induction and subsequent to administration, memory and degree of depression were measured by open field and tail suspension tests, respectively. At 24 hours after administration, p-CREB expression in the hippocampat CA3 region was analyzed by the immunohistochemical SABC method. RESULTS： Two rats from the Jiawei Wendan decoction-treated group, and one from the fluoxetine-treated group, died of unknown causes. The remaining rats in each group, except for one rat that was randomly selected from the fluoxetine-treated group, were included in the final analysis. Following administration, the model group exhibited significantly decreased numbers of hippocampal p-CREB-positive cells, horizontal and vertical movements, and significantly prolonged duration of immobility in tail-suspension test, compared with the normal control group （P 〈 0.01）. The numbers of p-CREB-positive cells, as well as horizontal and vertical movements, were significantly greater, and the duration of immobility was significantly shorter, in the Jiawei Wendan decoction and fluoxetine groups, compared with the model group （P 〈 0.05-0.01）. There was no significant difference in the above-mentioned three indices between the Jiawei Wendan decoction and fluoxetine groups （P 〉 0.05）. CONCLUSION： Jiawei Wendan decoction increased hippocampal p-CREB expression by influencing the rat hippocampal signal transduction pathway of CREB-BDNF. Jiawei Wendan decoction exhibited antidepressant effects equivalent to fluoxetine.

Wendan decoction improves learning and memory deficits in a rat model of schizophrenia

An experimental model of schizophrenia was established using dizocilpine （MK-801）. Rats were intragastrically administered with Wendan decoction or clozapine for 21 days prior to establishing the model. The results revealed that the latency of schizophrenia model rats to escape from the hidden platform in the Morris water maze was significantly shortened after administration of Wendan decoction or clozapine. In addition, the treated rats crossed the platform significantly more times than the untreated model rats. Moreover, the rate of successful long-term potentiation induction in the Wendan decoction group and clozapine group were also obviously increased compared with the model group, and the population spike peak latency was significantly shortened. These experimental findings suggest that Wendan decoction can improve the learning and memory ability of schizophrenic rats to the same extent as clozapine treatment.
